An online spreadsheet for your Excel workbooks

pulpSheet opens your Excel, LibreOffice and CSV files in the browser and saves them back to .xlsx, keeping whatever it cannot edit. Formulas, PivotTables, data and charts in one place.

What you can do with pulpSheet

Who is it for?

pulpSheet suits people who receive Excel workbooks and need to read, fix and send them back without Excel at hand: freelancers, non-profits, teachers, office teams. It also helps anyone analysing exports (bank statements, sales, stock): the import detects the delimiter, the encoding and the date order, and keeps codes with leading zeros intact.

If you build dashboards, your PivotTables and charts are written into the .xlsx file and open in Excel. Your workbooks stay on your device, and the spreadsheet works offline once loaded.

Your files

pulpSheet opens .xlsx, .xlsm, .xlsb, .xls, .ods, .csv and .tsv files. It saves to .xlsx or .xlsm (VBA is kept) and exports the current sheet to CSV; an .xls, .xlsb or .ods file is saved back as .xlsx. Main limitations: password-protected files do not open, slicers and timelines are not written for Excel, and a few items (sheet protection, sparklines) are kept without being applied. Remember to check the results of important formulas and macros.

File types recognised by pulpSheet:

  • .xlsx
  • .xlsm
  • .xlsb
  • .xls
  • .ods
  • .csv
  • .tsv

Format details and known limitations

Frequently asked questions

Can pulpSheet replace Excel?

For most everyday work, yes: data entry, formulas, formatting, sorting, filters, PivotTables, charts, printing and exchanging .xlsx files. Common VBA macros run (check their results) and a few recent functions are still missing. The format details list the known limitations.

How do I open an xlsx file without Excel?

Open pulpSheet, then use File › Open… or drag the file onto the window. If pulpSuite is installed as an app in Chrome or Edge, double-clicking the file is enough.

Are my files sent to a server?

No. Workbooks are read, calculated and saved in your browser. Only the requests you make to pulpAssist go through the assistant gateway that has been set up.

Do PivotTables created here open in Excel?

Yes, as real, refreshable PivotTables. Only slicers and timelines are not written to the Excel file.
